you cleaned all your belongings after quitting?
Dear lord, yes. I washed clothes in the closet I haven't worn in years, I rented a carpet cleaner, I bought a ton of Febreeze and similar products. I ran my leather jacket and vest through the dryer several times with 20 or so dryer sheets and several tennis balls (which helped with the smell quite a bit, but didn't remove all of it.) Yes, I did a ton of extra cleaning after I quit smoking, both in the house and in the car.
And I'm sort of shopping around for a new leather jacket. I'll sell the old one, cheap - to someone that smokes.
